Active prompting to decrease cell phone use and increase seat belt use while driving

Automobile crashes are the leading cause of death for those aged 3 to 33, with 43,005 (118 per day) Americans killed in 2002 alone. Seat belt use reduces the risk of serious injury in an accident, and refraining from using a cell phone while driving reduces the risk of an accident. Cell phone use while driving increases accident rates, and leads to 2,600 U.S. fatalities each year. An active prompting procedure was employed to increase seat belt use and decrease cell phone use among drivers exiting a university parking lot. A multiple baseline with reversal design was used to evaluate the presentation of two signs: "Please Hang Up, I Care" and "Please Buckle Up, I Care." The proportion of drivers who complied with the seat belt prompt was high and in line with previous research. The proportion of drivers who hung up their cell phones in response to the prompt was about equal to that of the seat belt prompt. A procedure that reduces cell phone use among automobile drivers is a significant contribution to the behavioral safety literature.     

The effects of prompting and feedback on drivers' stopping at stop signs

Complete stops at a high-traffic intersection on the campus of a public university were increased with a prompting and consequence intervention. Data were collected at two opposing stop signs (Stop A and Stop B); however, the intervention was implemented only at Stop A. During the intervention, a volunteer stood next to Stop A holding a poster that read, "Please Stop--I Care," with "Thank You For Stopping" on the reverse side. The poster was held by the volunteer so that drivers approaching Stop A could read the sign. Drivers approaching Stop B could see the volunteer but could not read the sign. When vehicles approaching Stop A made a complete stop, the volunteer flashed the "thank you" side of the poster to the driver. The strategy was evaluated using a multielement design. The intervention increased stops completed at Stop A from a baseline average of 13% to an intervention average of 52%. Stop B also showed improved stopping, from a baseline average of 6% to an intervention average of 28%. Data showed no relation between complete stops made and the drivers' use of turn signals and safety belts.     

PEER INTERVENTION EFFECTS ON COMMUNICATIVE INTERACTION AMONG HANDICAPPED AND NONHANDICAPPED PRESCHOOLERS

A peer-mediated intervention designed to promote communicative interaction on the part of three language-delayed children was evaluated. Two nonhandicapped preschoolers were taught strategies thought to facilitate interaction and were prompted to use these strategies during free play with three handicapped classmates. The intervention resulted in higher rates of interaction for each of the handicapped children that persisted above baseline levels after teacher prompting was withdrawn.     

INCREASING SPONTANEOUS VERBAL RESPONDING IN AUTUSTIC CHILDREN USING A TIME DELAY PROCEDURE

One oft-cited problem with teaching speech skills to autistic children isthe failure of the speech to be spontaneous. That is, the children's speech often remains underthe control of the verbal behavior of others rather than underthe control of other nonverbal referents inthe environment. We investigatedthe effectiveness of a time delay procedure to increasethe spontaneous speech of seven autistic children. Initially, the experimenter presented a desired object (e.g., cookie) and immediately modeledthe appropriate response “I want (cookie).” Gradually, asthe child imitatedthe vocalization, the experimenter increasedthe time between presentation of the object andthe modeled vocalization in an attempt to transfer stimulus control of the child's vocalization fromthe experimenter's model tothe object. Results indicated that allthe children learned to request items spontaneously and generalized this behavior across settings, people, situations, and to objects which had not been taught. These results are discussed in relation tothe literature on spontaneous speech, prompting, and generalization.     

PROGRAMMING PARTICIPATION IN FAMILY ACTIVITIES FOR CHILDREN WITH AUTISM: PARENTS' USE OF PHOTOGRAPHIC ACTIVITY SCHEDULES

The parents of 3 boys with autism were taught to help their children follow photographic activity schedules depicting a variety of home-living tasks. A multiple baseline across participants showed that the home-based intervention produced increases in children's engagement and social initiations and decreases in disruptive behavior, which were maintained for as long as 10 months.     

Reducing elevator energy use: A comparison of posted feedback and reduced elevator convenience

The effects of two different procedures for reducing elevator energy use were assessed using a multiple-baseline design. In the first procedure, feedback about the amount of energy consumed by the elevators each week was posted on each elevator door. Later, signs advocating the use of stairs to save energy and improve health were posted next to the feedback signs. In the second procedure, the time required to travel between floors was increased by adding a delay to the elevator door closing mechanisms. Results indicated that neither feedback alone nor feedback plus educational signs reduced the amount of energy consumed by the elevators. However, use of the door delay reduced consumption by one-third in all elevators.A second experiment replicated the effect of the door delay on energy consumption and, in addition, demonstrated that the door delay also produced a reduction in the number of persons using the elevator. The second experiment also showed that, following an initial period during which a full delay was in effect, a gradual reduction of the delay interval resulted in continued energy conservation. Reduced convenience as a general strategy for energy conservation is discussed.     

Effects of informational prompts on energy conservation in college classrooms

A multiple-baseline design was used with two target classroom groups (n = 28 and 27) in a study to reduce electrical energy waste in college classrooms. A dittoed letter, signed by a faculty member, was sent to each professor in the prompt condition. In the letter the professor was informed that he or she taught prior to an unscheduled period and was asked to turn off lights following the class. The results showed that after the prompt, the percentage of rooms with lights turned off increased by 13% and 6% in each target group. A further analysis of the 10 classrooms that had the lowest baseline rates of turning lights off indicated a 30% increase after the prompt. This study indicates that a minimum prompt procedure was effective in reducing electrical energy waste. The further significance of these results are also discussed.     

A PERFORMANCE IMPROVEMENT PROGRAM FOR AN INTERNATIONAL-LEVEL TRACK AND FIELD ATHLETE

This study outlined the development, implementation, and evaluation of an intervention strategy that was designed to improve the technical skill and performance of an international-level pole vaulter. Intervention, in the form of a prompting and shaping procedure, consisted of breaking a photoelectric beam with the hands at the moment of take-off. The height of the beam was gradually increased until the vaulter reached maximum arm extension at take-off. Increase in arm extension was matched by an increase in bar height clearance.     

REDUCTION OF CIGARETTE SMOKING IN A UNIVERSITY CAFETERIA

Passive smoking has been shown to be hazardous to the health of nonsmokers. Given this documented link between exposure to smoke-filled environments and deleterious health consequences, there is a need to develop effective procedures that establish and maintain no-smoking areas in various public settings. The present study focused on decreasing cigarette smoking in a section of a university cafeteria. Posting of no-smoking signs was found to decrease levels of smoking only minimally. However, when smokers were verbally prompted not to smoke, in the presence of the signs, marked decreases in smoking occurred in the target area.     

Evaluation of multiple‐alternative prompts during tact training

This study compared 2 methods of fading prompts while teaching tacts to 3 individuals who had been diagnosed with autism spectrum disorder (ASD). The 1st method involved use of an echoic prompt and prompt fading. The 2nd method involved providing multiple‐alternative answers and fading by increasing the difficulty of the discrimination. An adapted alternating‐treatments design showed that both procedures were more effective than a no‐intervention control condition. Providing multiple alternatives did not increase error rates or teaching time, and better maintenance was shown for tacts taught with the multiple‐alternative prompt.
